Green arrows point across the ceiling of a train.

The air flow on the new MAX trains sucks big time, especially for window seats on cold days. #TriMet #pdx #TheTransitLife

The heating area is near the floor and very feeble and/or fubared by the blast of air that flows along the arrows as shown in the picture. This air gets colder as it moves along the cold window to blow on one’s person in a most uncomfortable and continuous stream. Ugh. It’s even worse when one has a cold. I know.
